NCT04222972 · STUDY IN CONTEXT

A Study of Pralsetinib Versus Standard of Care for First-Line Treatment of Advanced Non-Small Cell Lung Cancer (NSCLC)

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

primary · POSTED

PFS was defined as the time from randomization to the date of first documented PD as determined by the investigator with the use of Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1) or death from any cause, whichever occurred first. PD was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest SOD at prior timepoints, including baseline. In addition to the relative increase of 20%, the SOD must also demonstrate an absolute increase of at least 5 millimeters (mm). Kaplan-Meier (K-M) method was used to estimate median PFS. 95% CI for median was computed using the method of Brookmeyer and Crowley.

ITT population included all randomized participants whether or not the assigned study treatment was received. As specified in the protocol, assessment of this outcome measure was limited to Arms A and B, as the objective was to compare pralsetinib with SOC platinum-containing anticancer treatment regimens.

secondary · POSTED

ORR was defined as the percentage of participants with a complete response (CR) or a partial response (PR) on two consecutive occasions ≥4 weeks apart, as determined by the investigator with the use of RECIST v1.1. CR was defined as disappearance of all target lesions or any pathological lymph nodes must have reduction in short axis to \< 10 mm. PR was defined as at least a 30% decrease in the SOD of all target lesions, taking as reference the baseline SOD, in the absence of CR. 95% CI for rates were constructed using the Clopper-Pearson method. Percentages have been rounded off.

secondary · POSTED

An AE is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. SAE is any significant hazard, contraindication, side effect that is fatal or life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is medically significant or requires intervention to prevent one or other of the outcomes listed above.

Safety-evaluable population included all participants who receive any amount of any study drug.

secondary · POSTED

ECOG is a 6-point scale (0-5) used to assess participants functional status, where, 0= Fully active, able to carry on all pre-disease performance without restriction; 1= restricted in physically strenuous activity but ambulatory \& able to carry out work of a light or sedentary nature, e.g., light housework, office work; 2= ambulatory \& capable of all self-care but unable to carry out any work activities. Up \& about more than 50% of waking hours; 3= capable of only limited self-care, confined to bed or chair more than 50% of waking hours; 4= completely disabled, cannot carry on any self-care, totally confined to bed or chair; 5= dead.

Safety-evaluable population included all participants who receive any amount of any study drug. As specified in the protocol, assessment of this outcome measure was limited to the treatment period, as the objective was to compare pralsetinib with SOC platinum-containing anticancer treatment regimens.

secondary · POSTED

DOR was defined as the time from the first occurrence of a documented objective response (OR) to PD or death from any cause, whichever occurred first, as determined by the investigator with the use of RECIST v1.1. CR was defined as disappearance of all target lesions or any pathological lymph nodes must have reduction in short axis to \< 10 mm. PR was defined as at least a 30% decrease in the SOD of all target lesions, taking as reference the baseline SOD, in the absence of CR. PD was defined as at least a 20% increase in the SOD of target lesions, taking as reference the smallest SOD at prior timepoints, including baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. K-M method was used to estimate median DOR. 95% CI for median was computed using the method of Brookmeyer and Crowley.

ITT population included all randomized participants whether or not the assigned study treatment is received. Overall number analyzed is the number of participants with an objective response of CR or PR. As specified in the protocol, assessment of this outcome measure was limited to Arms A and B, as the objective was to compare pralsetinib with SOC platinum-containing anticancer treatment regimens.
